为了测量此位移的变化，利用一个延长臂，把位移转移到较易测量的位置，然后采用直滑式电位器把位移变化转换成电压变化并测量出其值，最终转换成位移的变化值。
In order to measure the displacement , an extended arm is used to transfer it to a place where it is easy to be measuret and the variation of displacement is changed to voltage data by rheostat , finally the displacment data is obtained from voltage data .
